Because we sell thousands of edible duck eggs a week, it is important we produce eggs efficiently and consistently. In 1996 we developed the Golden 300 Hybrid as they lay more and larger eggs, have higher fertility and are calmer than the Khaki Campbell. The Khaki Campbell may be a good egg producer in small flocks but we were never satisfied with their production in our larger commercial flocks. Because of this inconsistency, we developed the Golden 300 Hybrid by crossing and utilizing the attributes of different duck breeds.
The Golden 300 Hybrid can be sexed at any age by its color as the males are shades of black and the females are shades of brown. Unfortunately, they do not retain this characteristic in future generations. So if you mate a Golden 300 Hybrid with another Golden 300 Hybrid, their progeny will hatch in blacks, yellows, and browns with no relationship between sex and color.
As adults, the females range in color from a very light brown to a very dark brown, often with areas of white on them. Males can appear much like a Rouen, or a dull looking Cayuga or with white and dark markings.
